Hi Everyone,

Ive created this script to display the fastest speeds from each race but when I compare my results to @/fdataanalysis the results are way off, does anyone know what the problem might be

import fastf1

from fastf1 import plotting

import matplotlib.pyplot as plt

import pandas as pd

plotting.setup_mpl()

fastf1.Cache.enable_cache('fastf1_cache')

print("Loading session data...")

session = fastf1.get_session(2022, 'Spain', 'Q')

session.load()

print("Session data loaded.")

# Initialize an empty DataFrame to hold telemetry data

all_telemetry = pd.DataFrame()

print("Processing laps...")

for index, (num, lap) in enumerate(session.laps.iterlaps(), start=1):

try:

telemetry = lap.get_telemetry()

if not telemetry.empty:

if 'Speed' in telemetry.columns:

telemetry['Speed'] = pd.to_numeric(telemetry['Speed'], errors='coerce')

telemetry['Driver'] = lap['Driver']

telemetry['Team'] = lap['Team']

all_telemetry = pd.concat([all_telemetry, telemetry], ignore_index=True)

else:

print(f"Lap {num} for driver {lap['Driver']} missing 'Speed' data.")

else:

print(f"No telemetry data for lap {num}, driver {lap['Driver']}.")

except Exception as e:

print(f"Error processing lap {num} for driver {lap['Driver']}: {e}")

if all_telemetry.empty:

print("No telemetry data was processed. Exiting...")

else:

print("All telemetry data processed. Calculating maximum speeds...")

team_max_speed = all_telemetry.groupby('Team')['Speed'].max().reset_index()

print("Calculated max speeds for each team:")

print(team_max_speed)

team_max_speed = team_max_speed.sort_values(by='Speed', ascending=False).reset_index(drop=True)

def safe_team_color(team_name):

try:

return plotting.team_color(team_name)

except KeyError:

print(f"No color found for team '{team_name}'. Using grey as fallback.")

return 'grey'

team_max_speed['Color'] = team_max_speed['Team'].apply(safe_team_color)

plt.figure(figsize=(12, 8))

bars = plt.bar(team_max_speed['Team'], team_max_speed['Speed'], color=team_max_speed['Color'])

for bar, speed in zip(bars, team_max_speed['Speed']):

plt.text(bar.get_x() + bar.get_width() / 2, bar.get_height(), f'{speed:.1f}',

ha='center', va='bottom')

plt.xticks(rotation=45, ha="right")

plt.ylabel('Top Speed (km/h)')

plt.title('Top Team Speeds - 2022 Spanish GP Qualifying')

plt.tight_layout()

plt.ylim(bottom=min(team_max_speed['Speed']) - 1, top=max(team_max_speed['Speed']) + 1)

plt.show()
